Abstract

The present invention is directed to an interface. In an aspect of the present invention, an interface system suitable for coupling a bus interface controller with a back-end device includes a bus interface controller and a back-end device in which the back-end device is coupled to the bus interface controller via an interface. The interface includes a command queuing interface suitable for enqueueing a transaction, a command completion interface suitable for reporting transaction completion and a data transfer interface suitable for transferring data. The data transfer interface includes an inbound data transfer interface suitable for transferring data and an outbound data transfer interface suitable for transferring data. The inbound data transfer interface and the outbound data transfer interface are suitable for processing commands simultaneously.

Description

CROSS REFERENCE TO RELATED APPLICATION

[0001] The present invention incorporates U.S. patent application Ser. No. 09 / 736,883, filed Dec. 14, 2000, titled “Interface for Bus Independent Core” by reference in its entirety.FIELD OF THE INVENTION

[0002] The present invention generally relates to the field of bus controllers, and particularly to an interface for a bus independent core.BACKGROUND OF THE INVENTION

[0003] Information handling systems, such as desktop computers, servers, network appliances, and the like, are driving the expansion of the modern economy. Because information handling systems are performance driven, system throughput is vital for differentiating products, such as products that exchange massive amounts of information, both internally and externally, with storage devices, network interface cards, and the like. Therefore, increases in the ability to transfer data both within the system itself and transfer data over a network may afford competitive advantages for systems ...
